i maintain multiple fate clients that have no iconv, not that it
matters much for the discussion here

If theres a developer who wants/needs a feature and is willing to
implement & maintain it then i will merge his work. (given its clean,
not buggy and iam aware of its existence and all that)

(there are a few corner cases where i wont but "returning the data as
 it is without mangling" (invalid if thats how it is)) is not one of

No developer should be able to block anothers work.
I thought disros like debian had such a rule and wanted to quote it
but seems i cant find it. Doesnt matter as i can speak myself what i
mean and i hope/belive thats a "rule" almost everyone agrees with.
